Research Opportunities in Machining of Composite Material Composite material is a macroscopic combination of two or more distinct materials, with a noticeable interface between them. Composite materials are extending the horizons of designers in all branches of engineering, and yet the degree to which this is happening can easily pass unperceived. Composite materials offer high strength, stiffness and toughness, good fatigue and impact resistance, good thermal and electrical conductivity, and good corrosion and wear resistance. These materials have wide applications in aerospace, transportation, construction and marine sectors, sporting goods and infrastructures. Advanced composites are optimized to achieve specific properties for special applications. These materials have balanced structural properties superior to either constituent material alone. Composites typically have a fiber or particle phase reinforced on relatively soft continuous matrix phase. Most of the reinforceme

EVs: The Future of Automobiles “Some people don’t like change, but you need to embrace change if the alternative is disaster.” ( Elon Musk ) Overview Over the last few years, Electric and hybrid electric vehicles (HEVs) have attracted attention worldwide. We’ve begun the process of searching E V as the future of transportation and electric mobility has become an essential part of an individual. Electric cars and Hybrid cars are the talk of metropolis not only because of reduced emissions but also for the reason that they give the owner a status in society that of one conscious of the environment a green crusader of sorts. Electric Vehicles have brought home the importance of its approaches in improving the quality of life. Boasting features like instant torque, lower fuel cost, low maintenance costs, silent ride, and premium performance. What is HEV & EV? HEVs are a type of hybrid which combines a conventional internal combustion engine (ICE) with an electric propu
Thermal Efficient High Temperature Resistant Light Weight Metal (γ-TiAl), a Potential Material for Aviation Application. World’s leading aviation industries predict that due to globalization as well as growth in the per capita income the use of airplanes will increase rapidly in years to come. Advisory Council for Aviation Research and Innovation reported that, the aeronautical industries by year 2050 have to meet the stringent quality standards with respect to (i) high fuel efficiency (ii) controlled emission of CO 2 , NO 2 and (iii) noise pollution as compared to standards of year 2000 [ACARE Aviation in Europe 2014: A vision for 2050 ]. Enhancements in propulsive efficiency or thermal efficiency are the two main criteria that govern the above quality standards. Propulsive efficiency of aircraft can be improved by providing higher by pass ratio with the geared turbo fans. The limitation of small ground clearance needs to be modified in order to enhance the propulsive effici
